Rahm Emanuel’s decision on run for Chicago mayor may come Friday

Washington, D.C.  White House chief of staff Rahm Emanuel, widely expected to leave the White House to make a long coveted run for Chicago mayor, could make an announcement on his decision as soon as Friday, a source close to him said.

Emanuel has not made a final decision, said the person familiar with Emanuel’s thinking, who spoke on condition of anonymity for that reason. The dominant factor at this point is the impact the move and the campaign would have on Emanuel’s wife and three young children, who live with him in Washington, the source said.

Should Emanuel leave the White House, Obama is expected to choose an interim chief of staff. That’s likely to be Peter Rouse, one of Obama’s senior advisers in the White House and his former chief of staff in the Senate.
